Abstract

The solubilities of the systems CeO2-SeO2-H2O and Ce2O3-SeO2-H2O were studied at 100°C. The field of crystallization of Ce(SeO3)2 was established in the system CeO2-SeO2-H2O, and fields of crystallization of Ce2(SeO3)3 and Ce2(SeO3)3H2SeO3 were established in the system Ce2O3-SeO2-H2O. The compound obtained were identified by means of chemical, X-ray and derivatograph analysis. The mechanism of thermal dissociation of Ce(SeO3)2, Ce2(SeO3)3 and Ce2(SeO3)3·H2SeO3 was studied.
